Embodiment
In description of the present utility model, it should be noted that, unless otherwise clearly defined and limited, term " installation ", " being connected ", " connection " should be interpreted broadly, and such as, can be fixedly connected with, also can be removably connect, or connect integratedly; Can be mechanical connection, also can be electrical connection; Can be directly be connected, also indirectly can be connected by intermediary, can be the connection of two element internals.For the ordinary skill in the art, concrete condition the concrete meaning of above-mentioned term in the utility model can be understood.In addition, in description of the present utility model, except as otherwise noted, the implication of " multiple " is two or more
For making the object of the utility model embodiment, technological scheme and advantage clearly, below in conjunction with the accompanying drawing in the utility model embodiment, technological scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is a part of embodiment of the present utility model, instead of whole embodiments.Based on the embodiment in the utility model, the every other embodiment that those of ordinary skill in the art obtain under the prerequisite not making creative work, belongs to the scope of the utility model protection.
As depicted in figs. 1 and 2, the utility model provides a kind of locking device, the locking gear comprising fastener 1, screw thread class fastening piece and be connected with fastener 1, and described locking gear loosens for stoping screw thread class fastening piece to reverse; Preferably, described locking gear is locking card 5, described locking card 5 offers the groove 7 (described groove 7 also can be able to be that whole circle is mated with the semi-match of nut 2) with nut 2 mating shapes on screw thread class fastening piece, described groove 7 rotates for stoping nut 2, as shown in Figure 3 and Figure 4, described groove 7 can be arranged to different angles coordinate with nut, as 15 ° or 30 ° etc.When adopting screw thread class fastening piece to be mechanically connected, the phenomenon that there will not be nut 2 to reverse, loosen, fastening better effects if, compared with traditional method, under larger frictional force, still can ensure the reliability connected, and original screw thread can not be destroyed, the working life of original thread fastening piece can be ensured, screw thread class fastening piece can be reused, more economic, practical; Meanwhile, the locking device structure that the utility model provides is simple, easily manufactured, with low cost, has higher practicability.
Wherein, a locking card 5 can be provided with a groove 7, also can be that a groove 7 arranges multiple groove 7, all can realize the object of the application, its aim be entrusted from design philosophy of the present utility model, should belong to protection domain of the present utility model.
Preferably, described locking card 5 is fixed on fastener 1 by least two screws 4, can ensure the firmness that locking card 5 is fixing like this, and then guarantees the stability that is threaded.
It should be noted that; locking card 5 also can be fixed on fastener 1 by other Placements; as welding, rivet or convex shoulder 6 is set on fastener 1; by coordinating of convex shoulder 6 and locking card 5; realize the fixing of locking card 5; all can realize the object of the application, its aim does not depart from design philosophy of the present utility model, should belong to protection domain of the present utility model.
When adopting convex shoulder 6 to fix locking card 5, locking card 5 thickness can be made concordant with outside convex shoulder 6, carry out axial restraint by rushing riveting or installing radial screw 4 pairs of cards additional.
This device first penetrates bolt 3 bolt 3 hole of fastener 1 in use, then by design pretightening force, nut 2 is twisted.Adjust nut 2 angle by swivel bolt 3 but still keep original screw-down torque constant, can match with the groove 7 of card to make nut 2 angle.Load after the card groove 7 processed in advance is aimed at nut 2 external form, through card, screw 4 is screwed into fastener 1, realize the fixing of card.
Particularly, as shown in Figure 1, nut stretches out fastener 120mm, hexagon nut 2 height 10mm, circumcircle radius 12mm, card thickness 5mm, groove 7 for circumcircle radius be the Hexagon of 13mm, can coordinate with nut 2 and install, external diameter is identical with convex shoulder 6 external diameter, is close to installation, the last screw 4 being screwed into radius 3mm between card and fastener 1, such screw 4 and convex shoulder 6 limit the dynamic movement of card jointly, and card limits again the rotation of nut 2 by the groove 7 coordinated with nut 2, finally reliably achieve the anti-rotation be threaded
Certain described nut 2 can be corner, five jiaos, hexagonal, heptangle or polygonal external form, can realize the object of the application equally, its aim does not depart from design philosophy of the present utility model, should belong to protection domain of the present utility model.
